New Generation Design Valves

Valves are a crucial part of the piping technology and are mainly used for isolating, control and safety applications in the fluid transfer field. For the past 15 years, the Hydrocore Valve Series has been developed, designed and patented and has been successfully implemented in various mines in South Africa .

The Hydrocore Valve Series is a new and entirely unique concept in the valve industry, which facilitates the automatic control and safety functions for fluid transfer system without any pilots, instruments, controllers, power supply or computers. Indeed, it can be described as extraordinary as it offers high-tech applications without the associated conventional high-tech technology and personnel.

Applications
The Hydrocore range of isolating, safety and control valves provides a simple, efficient, reliable and low-cost maintenance solution for most of fluid control applications, such as:-

• Manually operated shutoff valves
• Automatic actuated shutoff valve
• Pressure, flow and level control valves
• Pressure relief, pressure sustaining and excess flow shutdown valves
• Pump discharge control valves
• Plant flow control applications
• Timer-activated isolating valves.        

Uniqueness of the Hydrocore Valves
The Hydrocore Valve Series meets the global need for simple automation of existing plants and pipeline systems. The series also offers the following benefits:

• Reduces the number of plant operators
• Minimises the need for high-tech skilled personnel
• Reduces the sophistication level of the plant control
• Prevents damage to plant, pipeline & equipment through human error or negligence, thus saving on repair costs and production costs
• Reduces the capital cost for new plants.

Hydrocore Valves – Main Features
The Hydrocore Valve Series has many advantages, the most important of which are listed below:

• The Hydrocore valves do not require an external actuator, as the valve’s piston is a simple and powerful pneumatic/hydraulic actuator
• Handwheel and electrically actuated valves do not require the torque assistance of a gearbox
• The valve’s piston serves as the control pilot for all of the line-actuated safety and control valves with less vulnerability to precipitation or the build-up of corrosion products
• All of the safety and control valves can be used as a conventional or I/P actuated control valves by utilising conventional transmitters, switches and controllers
• All of the self-powered safety and control valves are not accessible to unauthorised tampering
• The sealing arrangement of the valves is of the pressure-assisted type, inducing low magnitude of parasite friction forces
• All of the valves are maintainable while in-line
• No other parts of the valve are inserted into the valve body except for the valve piston, which serves as a carrier to all of the seals and the valve seat
• Most of the Hydrocore valve parts are interchangeable between the various applications, irrespective of the pressure rating.
